1. Inconsistent thickness of materials: Inconsistent thickness of welded iron plates may exist, resulting in cracks during welding. This may be due to errors in material manufacturing or deformation in processing.
2. Inappropriate welding parameters: In the welding process, if the welding parameters are set inappropriately, such as welding current and welding time, it may lead to unstable welding and cracks.
3. Inaccurate welding position: When welding, if the welding position is not accurately centered, or there is a gap between the welding head and the iron plate, it will lead to a gap during welding.
4. Welding equipment problems: There may be problems in the welding equipment itself, such as damage of welding head and electrode wear, which lead to cracks during welding.
In order to solve the problem of cracks in the welded iron plate of fixed spot welder, the following measures can be taken:
1. Select suitable materials: When selecting iron plate materials, try to choose materials with uniform thickness to reduce the possibility of cracks during welding.
2. Adjust welding parameters: Adjust welding parameters reasonably according to specific welding materials and requirements to ensure firm welding and avoid cracks.
3. Ensure the welding position is accurate: Before welding, carefully check the welding position to ensure that there is no gap between the welding head and the iron plate, so as to avoid gaps.
4. Regularly inspect and maintain the equipment: regularly inspect the welding equipment to ensure that the welding head and electrode are in good condition, and replace the damaged parts in time to ensure the welding quality.
In a word, the cracks in the welded iron plate of fixed spot welder may be caused by inconsistent material thickness, inappropriate welding parameters, inaccurate welding position or welding equipment problems. By selecting suitable materials, adjusting welding parameters, ensuring accurate welding position and regularly checking maintenance equipment, the possibility of cracks during welding can be effectively reduced.
